green energy - The sun's rays could be the primary energy source on Earth and sunlight can be converted straight into electricity using solar panel systems. Electricity has become indispensable in daily life. It powers the machines that a lot of us use daily.

So, what are solar power systems? Let's say you can create your personal?

In the following paragraphs, we are going to show you a simple way of building your personal functional solar power.

THE COMPONENTS

A solar power is generally produced from six (6) components namely the PV (photovoltaic) cell or solar panel which generates the electricity, the glass supplies and protects the cells, the frame which supplies rigidity, the backsheet in which the cells are laid, the junction box the place that the wirings are enclosed and connected, and also the encapsulant which is adhesives.

Because most people won't have access to equipment in manufacturing solar power panels, you will need to note and understand those six components to ensure that anyone to be able to plan materials required to develop a do-it-yourself or home-made solar panel.

Materials needed on how to come up with a screen should be for sale locally or online and ought not exceed the expense of a brand new solar power or will not take a long time to create.

1.) PV Cell

An important thing to consider when building your own cell is the solar cell.

Photovoltaic (PV) cell or solar panel converts visible light into electricity. One (1) solar cell however is not enough to make a usable volume of electricity just like the microbot in Baymax (Hero 6) which only becomes useful when combined like a group. This basic unit generates a DC (direct current) voltage of 0.5 to 1 volt even though this can be reasonable, the voltage is still too small for the majority of applications. To create a useful DC voltage, the solar cells are connected in series and then encapsulated in modules making the screen. If a person cell generates 0.5 volt and is attached to another cell in series, the two cells should then have the ability to produce 1 volt and they will then be called a module. A standard module usually is made up of 28 to 36 cells in series. A 28-cell module can produce roughly 14 volts (28 x 0.5 = 14VDC) which is enough to charge a 12V battery or power 12V devices.

Connecting 2 or more solar panels require that you've a basic understanding of series and parallel connection which has similarities to connecting batteries to make up an electric battery storage system.

There are two most common cells that can be purchased available in the market; a monocrystalline cell as well as a polycrystalline cell. These two might have precisely the same size, 156mm x 156mm, however the main difference will be efficiency. You will need to purchase additional cells to provide as backup if you happen to fail on a few of the cells i.e. bad solder, broken cell, scratched, etc.

Monocrystalline solar cells are often black and octagonal fit. This type of solar cell consists of the very best and purest grade silicon driving them to expensive. However they are the perfect of all of cells and they are more often than not the choice of solar contractors when space is a crucial step to consider in achieving the power they would like to attain determined by their solar system design.

Polycrystalline PV Cells are seen as an their bluish color and rectangular. These cells are designed within a much simpler process which lowers the purity with the silicon content and in addition lowers the efficiency in the end product.

Generally, monocrystalline cells tend to be efficient than polycrystalline cells but this does not always mean that monocrystalline cells perform and outputs more power than polycrystalline cells. Solar cell efficiency has something related to how big is cellular matrix and each solar power or cells offer an efficiency rating depending on standard tests once they were manufactured. This rating is normally in percentage and the common values vary from 15% to 20%.

2.) Glass

The glass protects the PV cells while allowing optimal sunlight to give. These are generally made from anti-reflective materials. Tempered glass could be the selection of material nowadays for unknown and new manufacturers nevertheless, there are nevertheless those that utilize flat plate glass on their own solar power systems. Tempered glass are made by chemical or thermal means and is more often than not stronger than plate glass which makes it more expensive to generate though the price of manufacturing them today is affordable and cost-effective. Flat plate glass creates sharp and long shards when broken in contrast to tempered glass which shatters safely in small pieces upon impact, this is why in addition they refer to it as safety glass. It must be noted here that many amorphous solar panel systems uses flat plate glass due to the way the panel is constructed.

Tempered glass is what manufacturers used in mass producing their solar panels. Inside our DIY project, we suggest to work with Plexiglas also called acrylic glass which can be safer compared to regular normal glass from a local home improvement store. It's kind of expensive than regular glass but is safe from nature's elements and will not break easily. The Plexiglas can even be screwed or glued easily for the frame.

3.) Frame

A frame is often created from anodized aluminum which gives structure and rigidity on the solar module. These aluminum frames can also be designed to be appropriate for most solar mounting systems and grounding equipment for quick and safe installation over a roof or on the ground.

The frame in the factory-built solar panel is truly the aluminum part where all four sides with the cell sheet are inserted. Consider it as a skeletal rectangular frame. The cell sheet incidentally is made up of one other 4 components and therefore are layered and laminated within the following order from top to bottom; the tempered glass, top encapsulant, the solar cells, bottom encapsulant, then a backsheet. In your DIY solar panel, we are by using a wooden frame as well as the end-result would be something analogous into a picture frame where the picture is the cells glued to a non-conductive board, the glass for your Plexiglas top cover, along with the wooden part because frame and backsheet.

4.) Backsheet

The backsheet will be the layer of plastic film around the back surface of the module. This is actually the only layer protecting the module from unsafe DC voltage. The primary aim of the backsheet is to insulate and protect the handler from shock and provide the safest, efficient, and dependable electrical conductivity possible.

The backsheet is a wooden plywood in which the frame will likely be screwed on top and so on the sides. It should be noted here that a perforated hardboard (Pegboard) will be used to place and align the PV Cells which Pegboard will sit on the top of wooden backsheet and fitted within the wooden frame.

5.) Junction Box

The junction box is the place the terminal wires and bypass diodes are placed and concealed. The terminal wires are just the bad and the good wires based on the series connections of the Solar cells and is associated with another solar panel, a charge controller, battery power system, in order to an inverter, with regards to the system design. The bypass diode can be a protective mechanism that prevent power from okay the solar power when it is not producing electricity as with the situation if it's nightime.

You can find junction boxes suitable for factory-built solar power systems which can be available today to purchase online especially from China. If you aren't low on time, you can purchase on the web and wait for a delivery otherwise you can simply obtain a regular electrical junction box out of your local shop. The objective of the junction box would be to protect the terminals (bad and the good terminals) from water, dust, as well as other elements. This can be in which the two wires (red for positive and black for negative) is going to be originating from. The other end present in wires may also be paid by using a PV accessory called MC4 which can be also purchased online alongside the PV junction box.

6.) Encapsulant

Encapsulant sheets prevent water and dirt from infiltrating the solar modules and serve as shock-absorbers that protect the PV cells. They've this adhesive bonding capability to the glass, the Solar cells, and the backsheet much like a glue but stronger. Encapsulants are usually manufactured from Ethylene-Vinyl Acetate or EVA and are applied using lamination machines and processes. Solar panel manufacturers utilize a vacuum plus a large oven to properly seal and cure the EVA sheet onto the solar power systems. Most of us would not have the capacity to do that but many continue to have tried without success and some had varying levels of success.

Encapsulants are thin plastic sheets that are usually laminated on the top and bottom areas of the solar panel sheet. The lower encapsulant may be the layer in the backsheet in which the solar panels are actually placed and supported. Within our project, we will instead use a latex acrylic paint. This paint will not be applied to the solar cells because when attempted, will not bring about an identical distribution or application of the liquid for the top of the cells which can degrade performance. The paint will be applied to the wooden frame, wooden backsheet, also to the Pegboard. This Latex Acrylic paint will be able to protect the wooden parts from Ultra violet rays and may better resist blistering and cracking overtime. This paint, although water-soluble, can dry quickly and becomes water-resistant.
